选用高铬刚玉为耐火骨料,酚醛树脂和PVB为粘结剂,确定了高铬钢铸件V法醇基涂料的最佳配比,考察了涂料的多种性能,并进行了生产验证。结果表明,该涂料性能优良、成本低廉,有广泛的推广价值。
High-chromium corundum was selected as refractory aggregate, phenolic resin and PVB as binder. The best proportion of V-based alcohol-based coatings for high-chromium steel castings was determined. Various properties of coatings were investigated and production verification was carried out. The results show that the coating has excellent performance, low cost and wide promotion value.
